Symptoms

When attempting to render webpages via the Outlook folder pane using the Microsoft Dynamics 365 for Microsoft Outlook add-in (Outlook client), the view pane remains blank and "Waiting for a page to be retrieved from a CRM server..." displays. The pane never loads the corresponding webpage.

Cause

The Dynamics 365 for Outlook add-in relies on customized roaming home pages in order to render webpages within Outlook. The October 2017 Microsoft Outlook security update disables roaming home pages in Outlook to address a significant vulnerability with the application, and as such, inadvertently causes the add-in to fail.

More information on why this issue is occuring can be found at the following article from Outlook:

Installing the update above that matches your MSI version of Office Outlook will cause pages to be correctly displayed.
